With much reluctance I used the plastic OneUps on the PA ropes, but it was a very wary decision, and it was after I'd done the FOS nightmare for fear I wouldn't have anything left over for the others. I've tried ordering additional wires and clips before, but they would always get backordered, and sent in 2-3 months after the fact, or never at all. I'm expecting to receive several dozen in probably May-ish. Hopefully by then I haven't hung myself after trying to untangle all of them from the other monstrocities they currently occupy. There's an actual degreed engineer at my store working on flow and I've been telling him about some of the problems, and he just has this eyeroll, SMH expression the whole time =P
